I asked a similar question in an Ashdown thread, but think it would be better to have a thread dedicated to this instead. I'm looking for a bass amp (with a tweeter obviously) that could do part-time duty as a pseudo acoustic amp. Acoustic guitar amps (very much like keyboard amps and PAs) provied FULL-RANGE sound partly due to their very flat EQs and tweeters (again, like PAs and key amps). One of my electric guitars has a Q-filter wired to provide a faux-acoustic tone, but like a real or piezo acoustic, it only really comes to life in a PA or even acoustic guitar amp. Actual electric guitar amps tend to be EQ'd to compensate for the REAL sound of guitars. (Ever plug an electric guitar directly into a PA? It sounds very crisp and harsh. It needs the basic, starting EQ - and lack of speaker top end - that guitar amps provide.) Between either a Roland DB-500 or Ashdown MAG (with tweeter), which could get the most flat, PA-ish tonal reproduction? I understand the Roland DB Series has COSM models. The DB-500 has Solid State, Tube and Tube Drive Settings. I assume the cleanest is the solid state, but don't know how "EQ'd" it actually is. I'm not too sure about the MAG (or even an old stock Electric Blue 2x10" with tweeter). I know they're pretty much geared toward clean tones, but don't know how flat a reproduction (and how full the top end the tweeter provides) they yield. Anyone have any input?
